Face Recovery can't find a face, but crop then suddenly it can?

I have been trying to get Face Recovery to see faces. It finds none, but if I crop the same image in around the person, it suddenly can find the face and enhance it. Is this a bug, or does it just not look if the photo is large?

You can adjust the Face Recovery default setting by going to your Preferences > Autopilot > Face Recovery.

You will see the option to change the Default Face Detection as well as the Default Face-Recovery strength.
